Getting LPS to thrive in a high flow, high light environment is a challenge but what limits my mixing them is that LPS sting surrounding SPS. Nutrients are not a problem as everyone has done well in low nutrient environment.
I have a Duncan that is doing well in high light high flow and I can nestle it in SPS because it doesn’t sting. Euphyllia wouldn’t be an option here.
I have a goniopora at the bottom away from the SPS although it does sting and battle a Hollywood Stunner.
My softies tolerate high light high flow.
